My Computer will not boot

Boondock Saint · 08-07-2004, 05:27 AM

My computer started failing to boot about a month ago. It would start the cpu and disk drives and even the fan on the video card but the monitor would not register a signal. After many hours of eliminating hardware from the equation I determined that it must be the power supply. When everything was unplugged except the video card and ram the current power supply still failed to post. I then switched it with another older psu (250w) and it booted up just fine. So I decided it must be time for a new psu. I got the new one (450w A-Power) and it failed to boot again. Still the old 250 booted just fine when switched between the two. I even put my video card in another machine with the new psu and it wouldn't boot on that one either. So I figured there is either a compatibility issue between my video card (Radeon 9600xt) and the psu or that the psu is just bad or not powerful enough. I have since gone through 3 more psu's and nothing will boot my computer except the old 250w. I find it hard to believe that 3 psu's could all be bad or incompatible. Is there something else I should be trying or could there be another cause. My computer info is listed below. Please help a new poster.

mobo=k7vta3 8.0
cpu=amd 2000+
vpu=saphire radeon 9600xt
ram=512mb pc2700 ddr
sound=soundblaster audigy 2 platinum
hdd=wd 80gb 7200

Thanks

i would try getting a good psu
sparkle and antec are the best so i hear.
my pc runs on a 100watt just dandy...its in my signature below. Its not a compatability issue. Its not your vcard's fault that i know of. hmmm...do you have another video card to try out? if so try that, or if you have onboard video i would try that. good luck!

I would look into replacing the video card or motherboard, since it's looking more and more like one of those is at fault.

since it powers up with the old 250W psu, it sound very much like your motherboard maybe damaged, make sure that your motherboard is earthed properly.

make sure that your new PSU's are set to the correct voltage.. and you have both 5v and 12v connected to your motherboard..
